JOHN WILLIAM ANDERSON, OF HAMILTON, ONTARIO, CANADA, ASSIG-NOR OF ONE-HALF TO ALLITH MANUFACTURING COMPANY, LIMITED, 0F HAMILTON, ONTARIO,CANADA, INCORPORATED UNDER THE J OIN T-STOCK COMPANIES ACT OF THE PROV-INCE OF ONTARIO, CANADA.

HANGER-TRACK FOR SLIDING DOORS.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed April 5, 1913. Serial No. 759,111.

To all whom it may concern:

Be it known that I, J OHN WILLIAM ANDERSON, of the city of Hamilton, inthe county of ll entworth, in the Province of Ontario, Canada, haveinvented a certain new and useful Improvement in Hanger- Tracks forSliding Doors, of which the following is the specification.

My invention relates to improvements in hanger tracks for sliding doors,and the object of the invention is to devise a hanger track which willbe stronger, lighter and cheaper than those hitherto in use, and whichcan be applied to the track'brackets with greater case than has hithertobeen the case.

My invention consists of a hanger track of tubular or semi-tubularcross-section having a series of longitudinal corrugations extendingaround the periphery thereof, all as hereinafter more particularlydescribed, and illustrated in the accompanying drawing in which Figure 1represents a side view of a hanger, partly in section, showing a trackconstructed according to my invention applied thereto. Fig. 2 is aperspective view showing one form of track said track being ofsemi-elliptical cross-section. Fig. 3 is a perspective view showing atubular track and, Fig. 4 is a cross-section of a further modificationshowing a track in which the wheels of the hanger run in the interior ofthe same.

Like characters of reference indicate corresponding parts in eachfigure.

l is the hanger, and 2 is a yoke pivotally connected to the bottomthereof.

3 is the door secured to the yoke.

4: is the door jamb, and 5 is one of the track brackets mounted thereon.

6 and 7 are enlarged portions of the bracket having the upper and lowercross slits 6*, 7 a and 6", 7" respectively into which turned up edges 8and 8 of the upper sections 8 and the lower section 8 (Fig. 1) of thetrack 8 are designed to be inserted.

9 are the longitudinal corrugations extending around the periphery ofthe track.

10 is the hanger wheel suitably journaled to the hanger and having anouter periphery grooved correspondingly to the corrugations 9 on thetrack 8.

From the above description it will be seen that in constructing a trackin accordance with my invention, the corrugations 9 will greatly add tothe strength of the same and will also compel the hanger wheel to runtruer than has hitherto been the case. Further a track constructedaccording to my invention can be constructed of lighter material andconsequently there will be a great saving in the cost of the same. Alsoshould the wheel 10 have a tendency to leave the track, the outer orinner grooved portions of the periphery of the wheel will engage thecorresponding corrugations on the track, and thus restore the same toits normal position.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention within the scopeof the claims constructed without departing from the spirit or scopethereof, it is intended that all matter contained in the accompanyingspecification and drawings shall be interpreted as illustrative and notin a limiting sense. For instance, a track can be constructed to suitthe many types of hanger on the market, and therefore I do not wish toconfine myself to the forms shown.

What I claim as my invention and desire to secure by Letters Patent, is

1. In combination, hanger track brackets and a hanger track having aseries of longitudinal corrugations extending around the peripherythereof, said track being suitably mounted on the track brackets.

2. In combination, hanger track brackets having enlarged portions withcross slits therein, and upper and lower track portions having turnedover edges adapted to be inserted into the cross slits in the trackbrackets.

3. In combination hanger track brackets having enlarged portions withcross slits therein, and upper and lower track portions having turnedover edges adapted to be inthe Province of Ontario, Canada, this 10thsertecl into the 1cross slits in the track brackclay of March 1913. ets,each of tie track portions havin a series of longitudinal corrugationson the JOHN WILLIAM ANDERSON 5 outer surface thereof. I11 the presenceof In testimony whereof I have signed at EED. EAMES, Hamilton, in thecounty of Wentworth in H. M. F ETHERSTONI-IAUGH.
